Description
The utility model relates to a kind of loose structure communications optical cable, is specifically related to a kind of Lotus root shaped optical cable structure.
The communications optical cable that uses both at home and abroad is mainly loose cable structure at present.Loose cable structure mainly contains three kinds of forms: the one, and the central tubular optical cable; The 2nd, the loose sleeve layer strand type optical cable; The 3rd, slotted core cable.The central tubular optical cable, is strengthened protection by skin again and is combined in an oil-filled loose sleeve pipe (being loose tube fiber) by fibre bundle or the free bulk storage of fibre ribbon.The advantage of this optical cable is that structure and manufacturing process are simple, and deficiency is that the receiving optical fiber number is limited, and anti-adaptability to changes is relatively poor.The loose sleeve layer strand type optical cable is to be the primary structure unit with the loose tube fiber, around the stranded stranding of central reinforce member, strengthens protection by skin again and combines.The advantage of this structure is that the receiving optical fiber number is more, and anti-adaptability to changes and reliability increase than central tubular optical cable, and deficiency is that manufacturing procedure is many, and loose tube fiber is job-hoped easily, is out of shape, is fractureed, and has the hidden danger of quality of central tubular optical cable in addition too.Slotted core cable is that fibre bundle or fibre ribbon are put into the skeleton grooves (skeleton grooves extends along skeleton body longitudinal spiral or SZ strand) that once extrudes shaping in advance, combines by the outer protective sleeve protection again.The anti-adaptability to changes of the optical cable of this structure is stronger, stable performance, but make complicatedly, and the technological requirement height is easy to generate hidden danger of quality, and such as extruding in the process at skeleton, skeleton grooves is irregular, distortion and twisting pitch shakiness are insoluble practical problemss; In skeleton stranding process, the skeleton grooves easy deformation, fibre bundle or optical fiber are brought the groove difficulty into, job-hop easily, thereby make optical cable generation quality problems of producing etc.In a word, existing loose cable structure is difficult to that this tries to achieve unification aspect three in anti-adaptability to changes, structure and manufacturing process.
The utility model purpose provides a kind of stronger anti-adaptability to changes that has, stable performance, reliable in quality, simple in structure, the loose cable structure being convenient to make.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Lotus root shaped optical cable, comprise one group of fibre bundle or ribbon-unit, material water-proof material, central reinforce member and the cable core core body that xsect is the lotus root shape, the xsect of cable core core body is provided with one group along the hole that circumferentially distributes, described fibre bundle or ribbon-unit place one group of corresponding hole, fill material water-proof material between hole and fibre bundle or the ribbon-unit, central reinforce member is located at cable core core body central authorities as main tension stressed member.Described " fibre bundle or ribbon-unit " is meant by some optical fiber and constitutes and be in an optical cable basic composition in the free space together.Described " one group " refers at least two fibre bundles or ribbon-unit.Set " hole " is the free space of fibre bundle or ribbon-unit on the described cable core core body.The cable core core body is an one-piece construction, can manufacture with materials such as tygon.Can also outside the cable core core body, establish sealant again.
In the technique scheme, the hole of described circumferential distribution in the cable core core body around the central shaft longitudinal extension.Described longitudinal extension can be spiral extension, also can be the stranded extension of SZ, and its pitch can equate also can not wait, but equates for best.The xsect in hole can be circle, rectangle, trapezoidal, fan-shaped or their combination on the described cable core core body.At least be provided with a colour code line between the hole that circumferentially distributes on the cable core core body, to distinguish fibre bundle or ribbon-unit position.
Implementation method of the present utility model: make a lotus root shape in advance and rotate stranded core rod, fibre bundle or ribbon-unit and material water-proof material penetrate along the circumferential equally distributed hole of core rod, central reinforce member penetrates the center pit of core rod, utilize the geometric shape of core rod outlet and the precharge pressure of material water-proof material, adopt extruding to add the integrated approach that squeezes pipe, on the basis of material water-proof material heat absorption and water cooling typing, once be shaped.Rotate stranded core rod when central reinforce member rotates, making fibre bundle or fibre ribbon in the cable core core body, vertically form spiral or SZ twisting pitch.The outer set sealant of described cable core core body is also once finished in this manufacture method.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, simplified cable configuration.Because the utility model has designed a cable core core body that xsect is the lotus root shape, fibre bundle or ribbon-unit place the hole of lotus root shape cable core core body, and central reinforce member is located at cable core core body central authorities.The structure of whole envelope fibre bundle of this cable core core body or ribbon-unit, much simpler than slotted core cable and loose sleeve layer strand type cable configuration, simple repetition that neither the central tubular cable configuration.
2, many quality problems of having avoided existing loose cable structure to bring because of structure.Because the utility model adopts said structure, comparing with slotted core cable does not have the skeleton grooves of opening longitudinally on the cable core core body outer rim, avoided the distortion of existing open flume type skeleton generation skeleton grooves, fibre bundle or optical fiber to bring the problem of groove and job-hopping into; Compare the problem that does not exist loose tube fiber to job-hop easily, be out of shape, fracture with the loose sleeve layer strand type optical cable.
3, simplify manufacturing process, reduced manufacturing cost.Lotus root shaped optical cable described in the utility model is made according to the method described above, obviously lacks than slotted core cable and loose sleeve layer strand type optical cable manufacturing process, and technology is simple, and efficient is expensive low.And these advantages all be unable to do without the structural design of the whole lotus root shape of the utility model cable core core body.
4, creativeness combines the advantage of existing loose cable structure, has effectively overcome deficiency.Structure of the present utility model, manufacturing process and quality problems (mainly refer to bring because of architectural feature quality problems) are compared as can be seen with existing loose cable structure, Lotus root shaped optical cable described in the utility model is to reach due performance of optical cable and requirement according to the structure of slotted core cable and principle, is that the process of utilization central tubular optical cable solves skeleton grooves distortion and fibre bundle or optical fiber and brings the groove problem into.Therefore the utility model is compared with existing loose cable structure and is being realized effective unification aspect anti-adaptability to changes, structure and the manufacturing process three.This also is ingenious part of the present utility model and creationary further embodiment.
